Pre-takeoff checklist
OK, here's the story I have so far . . .
Engine removed from a Weatherly 620B and sent off for overhaul. All reports show that the original engine was operating "normally" but was due TBO.
An engine came back from the O/H shop (don't know if it was the original O/H engine or an exchange, but don't think that's relavant at this time, anyway). The mechanic installed the carburetor, mags, propeller, etc. removed from the original engine on the "new" engine and installed it in the aircraft.
The engine will not make static RPM - its running about 500 RPM to low. this particular prop is in low pitch (high RPM) with no governor oil pressure, and the mechanic has verified that he is getting 0 psi output to the prop with the prop control lever full forward, so the prop should be in low pitch and should be allowing the engine to reach static RPM at max throttle, but he cannot reach static RPM.
The engine shop says the engine checked out OK at their place, but that was with their mags, carb, and test club prop.
Anybody have any idea what could be wrong here? Remember that the components removed from the old engine (that was running "fine") were installed on this "new" engine as well.
